Green synthesis and characterization of silver nanoparticles using Laurus nobilis Leaves extract and degradation of methylene blue dye in polluted water

Abstract

In this work, extract from Laurus nobilis leaves was used as a capping and reducing agent during the manufacture of silver nanoparticles. The green-prepared silver nanoparticles were examined using UV-visible spectroscopy and scanning electron microscopy with energy dispersive X-ray (SEM-EDX). At 80 °C, the colour of the original solution changes to brown, signifying the creation of silver nanoparticles. The results  indicate that the unique surface plasmon resonance peak of the silver nanoparticles is located at 435 nm. SEM data shows that the silver nanoparticles are spherical and have a particle size of less than 61.36 nm. 90% of the sample's surface was determined to contain silver, according to EDX approval. 55% of the methylene blue was degraded using synthesized silver nanoparticles.
